50V is the upper limit for safety. Anything higher then 50V DC and it can kill you. Yes everything has to be reengineered for 36/42V power but once that is complete everything gets that much lighter. Higher voltage means less current to do the same work. Less current means smaller/lighter wires. I think most motors/actuators would also get smaller/lighter. In the couple of years it would take to convert over the DC/DC converters can be used on the components that haven't been converted yet. I.E. spend the money in the first year converting over the radio and lights, everything else (door locks, windows, fans get run with a DC/DC converter. Next year redo these subsystems. Now start working on the new things like Water pump and AC converting them to 36/42Volts.
